The utility model discloses an eccentric sprocket hoist mechanism, include: base, rise boom assembly, sprocket and the one end located on the base are connected in sprocket wheel face border, and the other end is connected in the lift cylinder of base, and the chain takes turns to the winding has the elevator chain, its characterized in that, and the sprocket is eccentric sprocket. The utility model provides an eccentric sprocket hoist mechanism, stroke alteration is circumference stroke, simple structure with the hoist mechanism straight line to on present hydro -cylinder directly pushes away sprocket hoist mechanism's basis, the optimal design has further carried out, the rotation center of sprocket setovers, become the hoist mechanism for similar cam, improved lifting height greatly, the biggest lifting height is 525mm. 本实用新型公开了种偏心链轮提升机构，包括：底座、设于底座上的起吊臂总成、链轮及端连接于链轮轮面边沿，另端连接于底座的提升油缸，链轮上缠绕有提升链，其特征在于，链轮为偏心链轮。本实用新型提供偏心链轮提升机构，将提升机构直线行程改变为圆周行程，结构简单，并且在现有油缸直推链轮提升机构的基础上，进步进行了优化设计，将链轮的旋转中心进行了偏置，成为了类似凸轮的提升机构，大大提高了提升
